NEWS file for libxml2

v2.15.0: Sep 15 2025

### Major changes

The API documentation is now generated with Doxygen. Building the
documentation requires the new --with-docs configuration option as well
as Doxygen, xsltproc and the DocBook 4 XSLT stylesheets.

The Python bindings are disabled by default now. Building the bindings
also requires Doxygen.

Support for Schematron is now disabled by default.

The parser option XML_PARSE_UNZIP is now required to read compressed data.

HTML serialization and handling of character encodings is more in line
with the HTML5 spec now.

More accessors for xmlParserCtxt were added.

### Deprecations

More internal functions and struct members were deprecated.

### Removals

The built-in HTTP client and support for LZMA compression were removed.

The custom Windows build system in `win32` was removed in favor of CMake.

### Planned removals

The Python bindings and support for Schematron validation are planned to
be removed in the 2.16 release.

The following features are considered for removal:

- Modules API (xmlmodule.h)
- Support for zlib compressed file I/O

RELAX NG support is still in a bad state and a long-term removal
candidate.

v2.14.0: Mar 27 2025

### Major changes

The HTML tokenizer now conforms fully to HTML5. Several non-standard
syntax warnings were removed. Note that HTML5 tree construction isn't
implemented yet.

Binary compatibility is restricted to versions 2.14 or newer. On ELF
systems, the soname was bumped from libxml2.so.2 to libxml2.so.16.

The serialization API will now take user-provided or default encodings
into account when serializing attribute values, matching the
serialization of text and avoiding unnecessary escaping.

The XML parser won't try to merge consecutive CDATA sections as before
to align with web standards. Each CDATA section will create exactly one
node or SAX callback.

Support for RELAX NG can now be disabled with a new configuration
option independently of XML Schemas support. It is still enabled by
default.

The "legacy" configuration option won't enable support for HTTP and
LZMA anymore. These features will be removed in the next release.

Parts of the xmllint executable were refactored, allowing the
combination of more options. OOM errors should be reported reliably now.

Several improvements were made to the build systems. Meson is fully
supported now.

Parts of the buffering code were reworked and simplified.

Overflow checks before reallocations were hardenend.

Some unprefixed symbols were renamed to avoid namespace pollution.

### New features

Input callbacks can now be set on a parser context and an improved API
to create parser input is available. The following new functions,
taking a parser input object, were added:

- xmlCtxtParseDocument
- xmlCtxtParseContent as replacement for xmlParseBalancedChunkMemory
  and xmlParseInNodeContext
- xmlCtxtParseDtd

The xmlSave API now has additional options to replace global settings.

Parser options XML_PARSE_UNZIP, XML_PARSE_NO_SYS_CATALOG and
XML_PARSE_CATALOG_PI were added.

An API function to install a custom character encoding converter is
now available. This makes it possible to use ICU for encoding conversion
even if libxml2 was compiled without ICU support, see example/icu.c.

### Deprecations

Access to many public struct members is now deprecated. Several accessor
functions were added to use instead.

More internal functions were deprecated.

### Removals

Metadata about the HTML4 content model was removed from the htmlElemDesc
struct and related functions were deprecated.

The FTP module and related functions were removed.

Support for the range and point extensions of the xpointer() scheme
was removed. The rest of the XPointer implementation isn't affected.
The xpointer() scheme now behaves like the xpath1() scheme.

Several legacy symbols and the functions in xmlunicode.h were removed.

ELF version information was removed.

The shell was moved from libxml2 to xmllint. Several related functions
are no longer available.

The libxml.m4 file containing autoconf macros was removed.

The --with-tree configuration option was removed.

The hack to detect single-threaded programs under glibc was removed.

### Planned removals

Support for HTTP and LZMA compression is planned to be removed in the
2.15 release.

The following features are considered for removal:

- Modules API (xmlmodule.h)
- Schematron support
- Support for zlib compressed file I/O
- Legacy Windows build system in win32

RELAX NG support is still in a bad state and a long-term removal
candidate.

v2.13.0: Jun 12 2024

### Major changes

Most of the core code should now report malloc failures reliably. Some
API functions were extended with versions that report malloc failures.

New API functions for error handling were added:

- xmlCtxtSetErrorHandler
- xmlXPathSetErrorHandler
- xmlXIncludeSetErrorHandler

This makes it possible to register per-context error handlers without
resorting to global handlers.

A few error messages were improved and consolidated. Please update
downstream test suites accordingly.

A new parser option XML_PARSE_NO_XXE can be used to disable loading
of external entities or DTDs. This is most useful in connection with
XML_PARSE_NOENT.

Support for HTTP POST was removed.

Support for zlib, liblzma and HTTP is now disabled by default and has
to be enabled by passing --with-zlib, --with-lzma or --with-http to
configure. In legacy mode (--with-legacy) these options are enabled
by default as before.

Support for FTP will be removed in the next release.

Support for the range and point extensions of the xpointer() scheme
will be removed in the next release. The rest of the XPointer
implementation won't be affected. The xpointer() scheme will behave
like the xpath1() scheme.

Several more legacy symbols were deprecated. Users of the old "SAX1"
API functions are encouraged to upgrade to the new "SAX2" API,
available since version 2.6.0 from 2003.

Some deprecated global variables were made const:

- htmlDefaultSAXHandler
- oldXMLWDcompatibility
- xmlDefaultSAXHandler
- xmlDefaultSAXLocator
- xmlParserDebugEntities

v2.12.0: Nov 16 2023

### Major changes

Most of the known issues leading to quadratic behavior in the XML parser
were fixed. Internal hash tables were rewritten to reduce memory
consumption.

Starting with this release, it should be enough to add the --with-legacy
configuration option to provide maximum ABI compatibility. For example,
if a code module was removed from the default configuration, the option
will add stubs for the removed symbols.

libxml2 will now store global variables in thread-local storage if supported
by the compiler. This avoids allocating the data lazily which can result in
a fatal error condition. A new API function xmlCheckThreadLocalStorage
was added so the allocation can be checked earlier if compiler TLS is not
supported. To prepare for future improvements, some API functions now expect
or return a const xmlError struct.

Several cyclic dependencies in public header files were fixed. As a result,
certain headers won't include other headers as before.

Refactoring of the encoding code has been mostly completed. Calling
xmlSwitchEncoding from client code is now fully supported, for example to
override the encoding for the push parser.

When parsing data from memory, libxml2 will now stream data chunk by chunk
instead of copying the whole buffer (possibly twice with encodings),
reducing peak memory consumption considerably.

A new API function xmlCtxtSetMaxAmplification was added to allow parsing
of files that would otherwise trigger the billion laughs protection.

Several bugs in the regex determinism checks were fixed. Invalid XML
Schemas which previous versions erroneously accepted will now be
rejected.

v2.11.0: Apr 28 2023

### Major changes

Protection against entity expansion attacks, also known as "billion laughs"
has been greatly improved. Malicious files should be detected reliably now
and false positives should be reduced. It is possible though that large
documents which make heavy use of entities are rejected now.

This release finally fixes symbol visibility on UNIX systems. Internal
symbols will now be hidden. While these symbols were never declared in public
headers, it was still possible to declare them manually. Now this won't work.

All symbol information has been removed from the ELF version script to fix
link errors with --no-undefined-version. The version nodes are kept so it
should still be possible to run binaries linked against older versions.

About 90 memory errors in code paths handling malloc failures have been fixed.
While these issues shouldn't impact security, this improves robustness under
memory pressure.

The XInclude engine has been reworked to properly support nested includes.

Several cases of quadratic behavior in the XML push parser have been fixed.

Refactoring has begun on some buffering and encoding code with the goal of
simplifying this part of the code base and improving error reporting.

Other highlights:

- Consolidated private header files.
- Major rework of the autoconf build.
- Deprecated several outdated and internal functions.

Special thanks to Google's Open Source Security Subsidies program for
sponsoring much of the work on this release!

Ongoing work on libxml2 relies on funding. For a list of important open

v2.10.0: Aug 17 2022

### Breaking changes

The Docbook parser module and all related symbols habe been removed completely.
This was experimental code which never worked and generated a deprecation
warning for 15+ years. The library's soname wasn't changed in order to allow
seamless upgrades to later versions. If this concerns you, consider bumping
soname yourself.

Some other modules are now disabled by default and will eventually be removed
completely:

- Support for XPointer locations (ranges and points): This was based on
  a W3C specification which never got beyond Working Draft status. To my
  knowledge, there's no software supporting this spec which is still
  maintained. You now have to enable this code by passing the
  `--with-xptr-locs` configuration option. Be warned that this part of
  the code base is buggy and had many security issues in the past.

- Support for the built-in FTP client (`--with-ftp`).

- Support for "legacy" functions (`--with-legacy`).

If you're concerned about ABI stability and haven't disabled these modules
already, add the following configuration options or bump soname yourself:

    --with-ftp
    --with-legacy
    --with-xptr-locs

Several functions of the public API were deprecated. Most of them should be
completely unused and will generate a deprecation warning now.

The autoconf build now uses the sysconfdir variable for the location of
the default catalog file. The path changed from hardcoded /etc/xml/catalog
to ${sysconfdir}/xml/catalog. The sysconfdir variable defaults to
${prefix}/etc, prefix defaults to /usr/local, so without other options
the path becomes /usr/local/etc/xml/catalog. If you want the old behavior,
configure with

    --sysconfdir=/etc

    provides namespace resolution and defaulted attributes, minimize memory
    allocations and copies, namespace checking and specific error handling,
    immutable buffers, make predefined entities static structures, etc...
   - rewrote all the error handling in the library, all errors can be
    intercepted at a structured level, with precise information
  available.
   - New simpler and more generic XML and HTML parser APIs, allowing to
    easily modify the parsing options and reuse parser context for multiple
    consecutive documents.

   - added xml2-config --libtool-libs option from Kevin P. Fleming
   - a lot of profiling and tuning of the code, speedup patch for
    xmlSearchNs() by Luca Padovani. The xmlReader should do far less
    allocation and it speed should get closer to SAX. Chris Anderson worked
    on speeding and cleaning up repetitive checking code.

   - output to a given encoding has been added/tested
   - lot of various fixes


2.0.0: Apr 12 2000:
   - First public release of libxml2. If you are using libxml, it's a good
    idea to check the 1.x to 2.x upgrade instructions. NOTE: while initially
    scheduled for Apr 3 the release occurred only on Apr 12 due to massive
    workload.
   - The include are now located under $prefix/include/libxml (instead of
    $prefix/include/gnome-xml), they also are referenced by
    #include <libxml/xxx.h>
    instead of
    #include "xxx.h"
  
   - a new URI module for parsing URIs and following strictly RFC 2396
   - the memory allocation routines used by libxml can now be overloaded
    dynamically by using xmlMemSetup()
   - The previously CVS only tool tester has been renamed
    xmllint and is now installed as part of the libxml2
    package
   - The I/O interface has been revamped. There is now ways to plug in
    specific I/O modules, either at the URI scheme detection level using
    xmlRegisterInputCallbacks()  or by passing I/O functions when creating a
    parser context using xmlCreateIOParserCtxt()
   - there is a C preprocessor macro LIBXML_VERSION providing the version
    number of the libxml module in use
   - a number of optional features of libxml can now be excluded at
    configure time (FTP/HTTP/HTML/XPath/Debug)


2.0.0beta: Mar 14 2000:
   - This is a first Beta release of libxml version 2
   - It's available only fromxmlsoft.org
    FTP, it's packaged as libxml2-2.0.0beta and available as tar and
  RPMs
   - This version is now the head in the Gnome CVS base, the old one is
    available under the tag LIB_XML_1_X
   - This includes a very large set of changes. From a  programmatic point
    of view applications should not have to be modified too much, check the
    upgrade page
   - Some interfaces may changes (especially a bit about encoding).
   - the updates includes:
    
      fix I18N support. ISO-Latin-x/UTF-8/UTF-16 (nearly) seems correctly
        handled now
      Better handling of entities, especially well-formedness checking
        and proper PEref extensions in external subsets
      DTD conditional sections
      Validation now correctly handle entities content
      change
        structures to accommodate DOM

        and proper PEref extensions in external subsets
   - DTD conditional sections
   - Validation now correctly handle entities content
   - change
        structures to accommodate DOM
   - Serious progress were made toward compliance, here are the result of the test against the
    OASIS testsuite (except the Japanese tests since I don't support that
    encoding yet). This URL is rebuilt every couple of hours using the CVS
    head version.


1.8.7: Mar 6 2000:
   - This is a bug fix release:
   - It is possible to disable the ignorable blanks heuristic used by
    libxml-1.x, a new function  xmlKeepBlanksDefault(0) will allow this. Note
    that for adherence to XML spec, this behaviour will be disabled by
    default in 2.x . The same function will allow to keep compatibility for
    old code.
   - Blanks in <a>  </a> constructs are not ignored anymore,
    avoiding heuristic is really the Right Way :-\
   - The unchecked use of snprintf which was breaking libxml-1.8.6
    compilation on some platforms has been fixed
   - nanoftp.c nanohttp.c: Fixed '#' and '?' stripping when processing
  URIs

   - added a nanoFTP transport module, debugged until the new version of rpmfind can use
    it without troubles


1.8.5: Jan 21 2000:
   - adding APIs to parse a well balanced chunk of XML (production [43] content of the
    XML spec)
   - fixed a hideous bug in xmlGetProp pointed by Rune.Djurhuus@fast.no
   - Jody Goldberg <jgoldberg@home.com> provided another patch trying
    to solve the zlib checks problems

    gnumeric soon


1.8.4: Jan 13 2000:
   - bug fixes, reintroduced xmlNewGlobalNs(), fixed xmlNewNs()
   - all exit() call should have been removed from libxml

   - fixed the DTD parsing code to work with the xhtml DTD
   - added xmlRemoveProp(), xmlRemoveID() and xmlRemoveRef()
   - Fixed bugs in xmlNewNs()
   - External entity loading code has been revamped, now it uses
    xmlLoadExternalEntity(), some fix on entities processing were added
   - cleaned up WIN32 includes of socket stuff


1.8.2: Dec 21 1999:
   - I got another problem with includes and C++, I hope this issue is fixed
    for good this time
   - Added a few tree modification functions: xmlReplaceNode,
    xmlAddPrevSibling, xmlAddNextSibling, xmlNodeSetName and
    xmlDocSetRootElement
   - Tried to improve the HTML output with help from Chris Lahey


1.8.1: Dec 18 1999:
   - various patches to avoid troubles when using libxml with C++ compilers
    the "namespace" keyword and C escaping in include files
   - a problem in one of the core macros IS_CHAR was corrected
   - fixed a bug introduced in 1.8.0 breaking default namespace processing,
    and more specifically the Dia application
   - fixed a posteriori validation (validation after parsing, or by using a
    Dtd not specified in the original document)
   - fixed a bug in


1.8.0: Dec 12 1999:
   - cleanup, especially memory wise
   - the parser should be more reliable, especially the HTML one, it should
    not crash, whatever the input !
   - Integrated various patches, especially a speedup improvement for large
    dataset from Carl Nygard,
    configure with --with-buffers to enable them.
   - attribute normalization, oops should have been added long ago !
   - attributes defaulted from DTDs should be available, xmlSetProp() now
    does entities escaping by default.

   - Lots of HTML improvement
   - Fixed some errors when saving both XML and HTML
   - More examples, the regression tests should now look clean

   - portability problems fixed
   - snprintf was used unconditionally, leading to link problems on system
    were it's not available, fixed


1.7.1: Sep 24 1999:
   - The basic type for strings manipulated by libxml has been renamed in
    1.7.1 from CHAR to xmlChar. The reason
    is that CHAR was conflicting with a predefined type on Windows. However
    on non WIN32 environment, compatibility is provided by the way of  a
    #define .
   - Changed another error : the use of a structure field called errno, and
    leading to troubles on platforms where it's a macro


1.7.0: Sep 23 1999:
   - Added the ability to fetch remote DTD or parsed entities, see the nanohttp module.
   - Added an errno to report errors by another mean than a simple printf
    like callback
   - Finished ID/IDREF support and checking when validation
   - Serious memory leaks fixed (there is now a memory wrapper module)
   - Improvement of XPath
    implementation
   - Added an HTML parser front-end
